Those aren't just any rain barrels. Saw one down the block that looked like a fancy copper planter with brass fittings. Must have cost more than my patio furniture. People are going all out for this.
Honestly saw one last week that was basically a giant terracotta urn with a spigot. Makes you wonder if this is still about saving water or just showing off. Like when did a simple plastic drum become too basic for suburbia? Tbh I'd rather spend that money on better soil or plants that actually need less watering.
